The A2 is the best pod system I've used.
Easy to fill, no leaking, charges quick, stellar flavour and the coils last.
The window is useless, needed to be on both sides. Sometimes its impossible snap off the mouthpiece to refill.
Not able to disable the firing button, which is very annoying, especially when your trying to snap off a new pod to fill. Its really easy to burn a dry coil.
